1 / 7 page SN54AS250A, SN74AS250A 1-OF-16 DATA GENERATORS/MULTIPLEXERS WITH 3-STATE OUTPUTS SDAS137A – DECEMBER 1983 – REVISED DECEMBER 1994 Copyright © 1994, Texas Instruments Incorporated 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • 4-Line to 1-Line Multiplexers That Can Select 1-of-16 Data Inputs • Applications: Boolean Function Generator Parallel-to-Serial Converter Data Source Selector • Buffered 3-State Bus Driver Inputs Permit Multiplexing From n Lines to One Line • Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (NT) and Ceramic (JT) 300-mil DIPs description The ′AS250A devices provide full binary decoding to select 1-of-16 data inputs or use sources as an input with an inverting W output. The selected sources are buffered with symmetrical propagation delay times. This reduces the possibility of transients occurring at the output. A buffered output-enable (OE) input can be used for n-line to 1-line cascading. Taking OE high places the output in the high-impedance state. In the high-impedance state, the output neither loads nor drives the bus lines significantly. OE does not affect the internal operations of the data selector/multiplexer. New data can be set up while the outputs are disabled. The SN54AS250A is characterized for operation over the full military temperature range of – 55 °C to 125 °C. The SN74AS250A is characterized for operation from 0 °C to 70°C. SN54AS250A ...JT PACKAGE SN74AS250A . . . DW OR NT PACKAGE (TOP VIEW) SN54AS250A . . .
